Not pretty, but ALIVE!
Brady didn't have the same drive in college that he took to the NFL. He was looked over in college with the whole Henson ordeal, but he still had a good career and earned the stigma of "captain comeback" during his senior year.
However, it was at the NFL combine when scouts literally made fun of him and he fell to the 6th round that he developed the biggest chip on his shoulder that any player has ever had. He started watching film 8 hours a day, every day, and was Bledsoe's shadow every second during practice. The guy lived for the chance where he could make fools of everyone who had doubted him. When he got his chance, he set out on a mission to prove them all wrong.
I don't see that same drive in McCarron, but that kind of drive is rare so that shouldn't be a knock on AJ at all.
Am I the only one who sees this as unrealized upside (College Tom) which is not available in (College Teddy) who is already doing these things?
